As of yet, a `Process` instance can't free memory.
The built-in callback has a self-reference to the intance not cleared after instance destruction.
I've tried to change both `buildCallback` and https://github.com/symfony/process/blob/v2.7.6/Process.php#L1373 usage to avoid self-referencing, but it can't be done without breaking BC, and the memory issue is still there.
A simple test script (that obiously can't be embedded in unit-tests)
```php
for ($inc = 0; $inc < 10000; $inc++) {
$process = new Symfony\Component\Process\Process('echo 1');
$process->mustRun();
$process->stop();
unset($process);
echo (memory_get_usage(true) / 1000000) . ' MB ' . $inc . PHP_EOL;
}
```
Before:
```
1.572864 MB 0
5.505024 MB 9999
```
After:
```
1.572864 MB 0
1.572864 MB 9999
```
Ok, in this simple scenario 4 MB of RAM is nothing, but in our business app full of IOC where `unset`-ting is hard, our RAM explodes.
After `stop()`, the callback is no longer necessary.
To be clear, the garbage collector in the previous example was already active.
Deactivating it manually, which somewhere is needed to avoid particluar segfaults, obiously leads to worse scenarios:
Before:
```
gc_disable();
1.572864 MB 0
29.360128 MB 9999
```
After:
```
gc_disable();
1.572864 MB 0
1.572864 MB 9999
```

Additionally, I think the arguments need to be the other way round (`templating` is an alias pointing to `templating.engine.twig`).

Because, you know, people do mistakes... I saw this happening during a workshop: when e.g. the factory tag has no `method` attribute, we generate an container that embeds a parse error.

Refactoring EntityUserProvider::__construct() to not do work, cause cache warm error

This fixes a "Database not Found" error when using `doctrine/orm` 2.5 while warming up your cache under certain situations. Basically, if you use the `EntityUserProvider`, then during cache warmup, Twig requires the `security.authorization_checker` which eventually requires this `EntityUserProvider`, which previously caused Doctrine to calculate the metadata for your User class. If no database exists (and you haven't specified the platform), you'll get the error.
More broadly, this simply tries to do less work in the constructor. It's a "bug fix", only kind of, but as it's completely an internal refactoring, it should be quite safe.
Thanks!
